TEP will own and operate the array and has contracted with E.ON Climate & Renewables for the system's construction.

The solar array, which is expected to come online later this year, will satisfy one-quarter of the base's energy needs, TEP says. The system at Fort Huachuca will be connected to an existing substation through a single interconnection on TEP's side of the meter.

Any excess energy the system generates, the utility notes, will flow back into the grid for use by other TEP customers.

Months after the U.S. Environmental Protection Agency released its Clean Power Plan, which will create new regulations for existing power plants, the agency says it has received loads of feedback to consider.
